Haha pretty much

Interesting approach, never thought about using the cable for something completely unrelated.

Thanks, that's pretty much exactly what I found: https://en.wikipedia.org/wiki/USB_hardware#Allowable_current_draw

The USB-C standard and particularly the USB PD (power delivery) is so complex it almost feels comical.

The PD standard document (freely available on usb.org) is over 800 pages long and features a lengthy part about the role of the cable alone which is mostly hidden from the user. Here's a short video about this issue: https://www.youtube.com/watch?v=6bZ0y9G-4Pc

That's true, they explain this in a different video: https://www.youtube.com/watch?v=y9vXDy_zt4I

Yeah, it's not really getting easier...

It indeed is, but there seem to be no testers available for resistance measurements.
